(3)第三类:内置在ASE包中,且靠Python实现的计算器。 EMT、EAM、Lennard-Jones、Morse和HarmonicCalculator。 (4)第四类:内置在ASE包中的其他计算器。 ase.calculators.checkpoint.CheckpointCalculator、 ase.calculators.fd.FiniteDifferenceCalculator、 ase.calculators.loggingcalc.LoggingCalculator、 ase.calculators.mixi...
通常,calculators通过调用外部电子结构代码或力场代码来工作。要运行计算,我们必须首先创建一个calculator,然后将其附加到Atoms对象。这里我们使用GPAW并设置一些计算参数: from gpaw import GPAW calc = GPAW(mode='lcao', basis='dzp', txt='gpaw.txt', xc='LDA') atoms.calc = calc 不同的电子结构软件具有不...
